BACKGROUND

Embodiments of the present disclosure relates generally to a cooking device and components thereof, and more specifically, to a multifunction device configured to perform the operation of a plurality of distinct cooking devices, the multifunctional cooking device optionally employing various components for cooking in the distinct cooking modes.

Conventional cooking devices, such as pressure cookers and air fryers each perform a single cooking operation, and as such, these devices employ different components and methods for cooking food items. As such, multiple devices are required to perform various cooking operations. For consumers that wish to enjoy food cooked in different ways via different operations, an accumulation of these devices can occur. Such an accumulation of cooking devices is often prohibitive from a standpoint of cost and storage space. For at least these reasons, it would be desirable to integrate the functionality of several cooking devices into a single user-friendly cooking device.

DETAILED DESCRIPTION

With reference now to FIGS. 1-3, an example of the cooking system 20 is illustrated. As shown, the cooking system 20 includes a base 22 and a lid 24. The base 22 includes a housing 26 made of any suitable material, such as glass, aluminum, plastic, or stainless steel for example. A liner 28 may be disposed within the hollow interior 30 of the housing 26. The liner 28 may be formed from any suitable conductive material, such as aluminum for example. In an embodiment, the liner 28 forms an interior surface of the housing 26 and thereby defines the hollow interior 30 of the housing 26. Alternatively, the liner 28 may be offset from the interior surface of the housing 26. However, it should be understood that other components of the cooking system 20, or surfaces thereof, may also define the hollow interior 30.

A cooking container 32 is receivable within the hollow interior 30 of the housing 26. Although the cooking container 32 is described herein as being removable from the housing 26 of the base 22, embodiments where the cooking container 32 is integrally formed with the housing 26 are also contemplated herein. In an embodiment, a height of the cooking container 32 is greater than the height of the hollow interior 30 of the housing 26. Accordingly, when the cooking container 32 is installed within the interior 30, an end of the container extends beyond the adjacent end surface 38 of the housing 26, as shown in FIG. 3. The cooking container 32 has an interior or cooking chamber 34 designed to receive and retain one or more consumable products, such as food products for example, therein. Examples of food products suitable for use with the cooking system 20, include but are not limited to, meats, fish, poultry, bread, rice, grains, pasta, vegetables, fruits, and dairy products, among others. The cooking container 32 may be a pot formed from a ceramic, metal, or die cast aluminum material. In an embodiment, an interior surface of the cooking container 32 includes a nano-ceramic coating and an exterior surface of the cooking container 32 includes a silicone epoxy material. However, any suitable material capable of withstanding the high temperatures required for cooking food products is contemplated herein. Further, one or more handles may be associated with the cooking container 32 to allow a user to easily grasp and manipulate the cooking container 32 relative to the housing 26.

One or more accessories, may be compatible for use with the cooking system 20. Examples of such accessories include, but are not limited to, a diffuser, a crisping insert or basket (see numeral 36 in FIGS. 2 and 3), a grill plate, and a griddle for example. In such embodiments, the accessories may be receivable within the hollow interior 30 of the housing 26, or alternatively, within the cooking chamber 34 of the cooking container 32.

Referring with more detail to the lid 24, it should be noted that the lid 24 is connectable to a surface of the cooking container 32 and/or housing 26 to close off entry to the cooking chamber 34 of the cooking container 32. Accordingly, a heating volume may be defined between the cooking chamber 34 of the cooking container 32 and the closed lid 24, such as the bottom surface of the closed lid 24, or alternatively, between the hollow interior 30 defined by the housing 26 and the closed lid 24. As used herein, the term “heating volume” describes a volume within the cooking system 20 through which a fluid may circulate during a cooking operation (to be described in detail below). In an embodiment, a diameter of the lid 24 is generally complementary to a diameter of the housing 26 such that the lid 24 covers not only the cooking container 32, but also an upper surface 38 of the housing 26.

The lid 24 is movable relative to the base 22 between an open position (FIG. 2), in which the cooking container 32 is accessible, and a closed position (FIG. 1, 3) to selectively cover the hollow interior 30 and cooking chamber 34. The lid 24 may be distinct and separable from the base 22, or alternatively, the lid 24 may be movably connected to the base 22. In the illustrated, non-limiting embodiment of FIG. 2, the lid 24 is pivotable or rotatable (via a hinge 35 for example) relative to the base 22 about a pivot axis P. However, other types or movement of the lid 24 are also within the scope of the disclosure.

One or more fastening mechanisms (not shown) may but need not be used to secure the lid 24, or a portion thereof, to the base 22 when the lid 24 is in the closed position. In an embodiment, the fastening mechanism is selectively engaged when the lid 24 is in the closed position. Alternatively, or in addition, the fastening mechanism is selectively engaged based on a selected cooking operation of the cooking system 20, such as pressure cooking for example. Any suitable type of fastening mechanism capable of withstanding the heat and pressure associated with the cooking system 20 is considered within the scope of the disclosure.

As best shown in FIG. 3, the lid 24 may include a generally convex outer lid or lid housing 40 made from any suitable material. In some embodiments, at least a portion of the material of the lid housing 40 may be substantially identical to the material of the housing 26. An inner lid liner (or sealing liner) 42 is arranged within the hollow interior 44 of the lid housing 40. Although the inner lid liner 42 is illustrated as also having a generally convex shape, embodiments where the shape of the inner lid liner 42 is different than the shape of the lid housing 40 are also within the scope of the disclosure. Further, the inner lid liner 42 can be made of arty suitable material, such as glass, aluminum, plastic, or stainless steel, or arty combination thereof for example. The inner lid liner 42 may but need not be made from the same material as the lid housing 40.

In an embodiment, a sealing surface 46 of the lid 24 is connectable to the upper surface 38 of the housing 26 or directly to the cooking container 32 to form a pressure-tight seal between the lid 24 and the cooking container 32 or housing 26. As a result, an inner surface 54 of the inner lid liner 42 defines a relatively upper boundary of a heating volume through which a fluid can circulate. In an embodiment, the sealing surface 46 is arranged at the end of the inner lid liner 42 adjacent to the cooking container 32. The sealing surface 46 may be formed by a portion of the inner lid liner 42 itself, or as shown in the FIGS. 4-6, a flexible/resilient gasket 50 connected to a portion of the inner lid liner 42, such as the end thereof, may define the sealing surface 46. This gasket 50 may be made of rubber, silicone, or other similar materials, and may include a flange that is received within an interior of the cooking container 32. It should be appreciated that the pressure tight seal formed between the lid 24 and the cooking container 32 or housing 26 may occur during all cooking modes, or just select cooking modes such as those modes that involve pressure or conductive cooking. In embodiments wherein the pressure tight seal is just formed in select cooking modes, this seal may not be formed in air fry or convection modes, and the lid 24 may simply rest on the upper surface of the housing 38 or cooking container 32 when the lid 24 is closed.

The system 20 may also include embodiments wherein additional steps beyond simply closing the lid 24 may have to be taken in order to form the pressure tight seal. In other words, closing the lid 24 relative to the base 22 may not automatically form a pressure-tight seal there between. In such an exemplary embodiment, the lid 24 additionally includes a lid lock 52. As best shown in FIGS. 4-6, the lid lock 52 is arranged within the interior of the lid housing 40, such as generally concentrically with a portion of the inner lid liner 42 relative to a central axis of the lid 24. In the illustrated, non-limiting embodiment, the lid lock 52 has a ring shaped or annular body aligned with a bottom surface of the lid housing 40 and/or the inner lid liner 42. An inner surface 53 of the lid lock 52 may be positioned generally adjacent to or in directly contact with an exterior surface 55 of the inner lid liner 42. In an embodiment, the lid lock 52 is movable, such as rotatable about an axis relative to the lid housing 40 and the inner lid liner, to selectively apply a pressure to move the sealing surface 46 into engagement with the cooking container 32 to form a pressure-tight seal therebetween. However, in other embodiments, it should be understood that closing the lid 24 relative to the base 22 may form a pressure-tight press-fit connection between the sealing surface 46 and/or the cooking container 32.

Regardless of whether rotation of the lid lock 52 is required to form a pressure-tight seal, the lid lock 52 is operable as a locking mechanism that retains or lock the lid 24 in the closed position relative to the base 22. For example, as shown in FIGS. 5-8, the lid lock 52 includes a first portion of a bayonet locking system such that by rotating the lid lock 52, one or more engagement members 56 (FIGS. 5-7) formed on the lid lock 52 abut or intermesh with one or more engagement members 58 (FIG. 8) of a complementary second portion of the bayonet locking system extending from an upper portion of the housing 26 to restrict movement of the sealing surface 46 away from the cooking container 32 in response to an increased pressure within the heating volume. In other embodiments where a pressure-tight seal is formed upon closing the lid 24 relative to the base 22, another locking mechanism, distinct from the lid lock 52 may be operable to maintain the sealing surface 46 in sealing engagement with the cooking container 32 once a pressurized environment is generated.

At least a portion of or a part connected to and extending from the lid lock 52 may be accessible at an exterior surface of the cooking system 20 for manipulation by a user to selectively lock the lid 24 to the base 22 so as to form and/or maintain a pressure-tight heating volume defined between the interior surface 54 of the inner lid liner 42 and the cooking chamber 34 of the cooking container 32 (to be described in more detail below). In the illustrated, non-limiting embodiment, best shown in FIGS. 1 and 5-9, the lid lock 52 includes an outwardly extending protrusion 60, also referred to herein as a mode selector, arranged within an opening 62, for example a slot, formed at an exterior surface of the lid housing 40. In such embodiments, a user may transform the lid lock 52 between locked and unlocked configurations by translating the mode selector 60 within the opening 62 between a first position and a second position. Although the inner lid liner 42 is described herein as being stationary and the lid lock 52 is described as being movable relative to the inner lid liner 42, embodiments where the inner lid liner 42 is coupled to or formed as a unitary body with the lid lock 52, such that both the inner lid liner 42 and the lid lock 52 are movable relative to the lid housing 40 in unison are also within the scope of the disclosure.

With reference now to FIGS. 1 and 10A-11B, the lid 24 may additionally include a pressure release mechanism 64, such as a vent or valve. In embodiments where a movement of the lid 24 is restricted to maintain the pressure-tight seal, the pressure release mechanism 64 may be formed in the stationary inner lid liner 42, such as in an upper surface or side surface or the inner lid liner 42 for example. However, it should be understood that in embodiments where the inner lid liner 42 is rotatable about an axis relative to the lid housing 40, the pressure release mechanism 64 coupled to the inner lid liner 42 may be adapted to couple to the inner lid liner 42 only when in the sealed position, or alternatively, to move with the inner lid liner 42.

The pressure release mechanism 64 may be configured to automatically open to release air from within the heating volume formed between the inner lid liner 42 and the cooking container 32 when the pressure therein exceeds a predetermined threshold, such as during operation of the cooking system 20 in a first cooking mode performing a pressure cooking operation. Alternatively, or in addition, the pressure release mechanism 64 is manually operable, such as rotatable about a vertically oriented axis for example, to release air or fluid from within the heating volume. An example of a manually operable pressure release mechanism 64 is shown in FIGS. 10A-11B. In the illustrated, non-limiting embodiment, a connector 66 operably coupled to a movable portion 68 of the pressure release mechanism 64, such as a knob for example, is arranged at an exterior surface of the lid 24 for access by an operator. As the knob 66 is rotated between a first, open position (FIG. 10A) and second, closed position (FIG. 10B), the movable portion 68, such as a valve stem for example, is configured to rotate and/or translate to selectively seal or expose an opening formed in the inner lid liner 42 in fluid communication with the interior of the cooking container 32.

The cooking system 20 includes at least one heating element operable to impart heat to the heating volume during one or more of a plurality of cooking modes of the cooking system 20. In the illustrated, non-limiting embodiment, a first or upper heating element 70 is positioned generally at or above an upper extent of the cooking container 32, such as proximate a center of the interior 34 of the cooking container 32 for example. As shown, the at least one first heating element 70 is mounted within the lid 24 (and may also be referred to as lid heating element 70), and therefore completely outside of the cooking container 32, and vertically offset from the upper extent thereof. In the illustrated, non-limiting embodiment, the first heating element 70 is arranged within the interior 72 of the inner lid liner 42, such as at a position offset from an interior surface 54 of the inner lid liner 42. In the illustrated non-limiting embodiment, a second or lower or base heating element 74 is also disposed within the housing 26, generally adjacent the bottom 76 of the cooking container 32. However, it should be understood that embodiments where a heating element is arranged at another location within the base 22 and/or the lid 24 are also contemplated herein.

The at least one first and second heating element 70, 74 may be capable of performing any suitable type of heat generation. For example, a first and second heating element 70, 74 configured to heat the cooking container 32 or one or more food items located within the cooking chamber 34 of the cooking container 32 via conduction, convection, radiation, and induction are all within the scope of the disclosure. In the illustrated, non-limiting embodiment, the first heating element 70 is operable to cook food within the cooking container 32 via a non-contact cooking operation. As used herein, the term “non-contact cooking operation” includes any cooking operation where a heating element or heat source is not arranged in direct or indirect contact with a food item, such as, but not limited to, convective and radiant heating. In such embodiments, the cooking system 20 additionally includes an air movement mechanism 78, such as a fan for example, operable to circulate air within the cooking volume. The air is heated as it flows along its path of circulation, such as by flowing over a portion of the at least one first heating element 70. In such embodiments, the first heating element 70 is operable to perform a convective heating operation. Convective heating operations may also generally be referred to as “dry cooking operations,” which include any cooking mode that creates a “dry cooking environment” within the container 24, such as but not limited to air frying, broiling, baking/roasting and dehydrating. To create a dry cooking environment, air and moisture are actively exhausted or vented from the cooking enclosure to outside the cooking system 20, thereby maintaining a minimum level of moisture within the container 24. Temperatures associated with the various exemplary but non-limiting convective/non-contact/dry cooking modes are between about 100° F. and 475° F. For example, temperatures associated with an air frying operation may be between about 300° F., temperatures associated with a roasting operation may be between about 250° F. and about 400° F., temperatures associated with a dehydrating operation may be between about 100° F. and about 200° F., and a broiling operation may be at a temperature of about 450° F. However, the temperatures provided herein are intended as an example only and it should be understood that any of the cooking modes described herein may be performed at other temperatures.

In the illustrated, non-limiting embodiment, the air movement mechanism 78 is arranged within the interior 72 of the inner lid liner 42, downstream from the first heating element 70 relative to the path of circulation of the air. The air movement mechanism 78 is driven by a motor 80 having a separate cooling mechanism coupled thereto. In an embodiment, best shown in FIG. 12, the motor 80 is arranged on an opposite side of the inner lid liner 42 as the air movement mechanism 78. Accordingly, a motor shaft 82 of the motor 80 extends through an opening 84 formed in the inner lid liner 42. In an embodiment, a sealing device, such as a gasket 86 for example, is positioned between the motor shaft 82 and the inner lid liner 42 to minimize or eliminate friction of the motor shaft 82 as it rotates, while maintaining a pressure tight seal with the inner lid liner 42. In an embodiment, the gasket 86 is designed to deflect in response to pressure. In such embodiments, when the heating volume is not pressurized, such as during air fry operations where the motor shaft 82 is rotated about its axis, no contact is formed between the motor shaft 82 and the gasket 86. Accordingly, when the heating volume is not pressurized, the motor shaft 82 is configured to rotate freely absent friction from the gasket 86. Further, the motor 80 is not configured to operate when the heating volume is pressurized. Therefore, in response to the pressure within the heating volume, the gasket 86 will deflect to form a retaining feature that creates an air-tight seal with the motor shaft 82, thereby allowing pressure to build within the heating volume.

In an embodiment, the second heating element 74 is operable to cook food within the cooking container 32 via a contact cooking operation. As used herein, the term “contact cooking operation” includes a cooking operation where heat is transmitted via direct or indirect contact between a heating element or heat source and a food item, such as, but not limited to, conductive cooking. Inductive cooking via the lower heating element 74 is also contemplated herein. It should be understood that embodiments where the first heating element 70 is operable to perform a contact cooking operation and embodiments where the second heating element 74 is operable to perform a non-contact cooking operation are also within the scope of the disclosure. Non-contact or conductive cooking operations may generally be referred to as “wet cooking” operations, such as but not limited to pressure cooking, steam cooking, slow cooking, searing, and sautéing. To create a wet cooking environment the majority of the moisture within the container, i.e. liquid added to the container 24 or moisture released from the food within the container 24, is retained within the container as the food is cooked. Although during conductive cooking operations a minimal amount of air having moisture entrained therein may be vented from the system, such air is passively removed from the cooking enclosure. Pressure cooking as used herein will allow for cooking in a pressurized environment at or above 40 kPa (with a range of 40 kPa to 90 kPa).

Further, in embodiments including a first heating element 70 and a second heating element 74, it should be understood that the first and second heating elements 70, 74 may be operable independently or in combination to apply one or more predetermined power settings to cook the food products within the cooking container 32. In operation, the first and second heating elements 70, 74 may be capable of cooking the food independent of the loading of the food. In other words, the first and second heating elements 70, 74 may be capable of cooking the food independent of the amount of food within the cooking container 32. The cooking operations that may be performed by the cooking system 20 include but are not limited to pressure cooking, steam cooking, slow cooking, searing, sautéing air frying, broiling, baking/roasting, dehydrating, and grilling.

With reference to FIGS. 4-6, the lid 24 includes a heater/fan cover 90 that protects a user from the first heating element 70 and an air movement mechanism 78 and protects the first heating element 70 and an air movement mechanism 78 from the areas of the cooking system 20 where food is cooked. In the illustrated non-limiting embodiment, the cover 90 is mounted within the lid 24, such as adjacent, and more specifically upstream from, the first heating element 70 relative to an air flow. The cover 90 may be sized to substantially overlap, and therefore protect, the entire surface of the first heating element 70 facing the cooking volume. In an embodiment, a contour of the cover 90 is generally complementary to the shape of the first heating element 70 to protect the surface of the first heating element 70 closest to or facing the cooking chamber 34. However, in other embodiments, the contour of the cover 90 may be complementary to the interior of the lid 24.

As best shown in FIGS. 5 and 6, the cover 90 generally includes a body formed from any suitable heat-resistant material. The body of the cover 90 has a plurality of openings 92 formed therein to allow hot air circulating within the cooking chamber 34 of the cooking container 32 to pass there through. In the illustrated, embodiment, the cover 90 has a nano-ceramic coating and is mounted via any suitable mounting mechanism, such as via one or more fasteners for example, and may be removably or permanently arranged therein. Accordingly, when the lid 24 is in the closed position, the cover 90 is arranged generally above the first open end of the cooking container 32.

To prevent the pressure within heating volume from increasing during a non-pressurized cooking operation as a result of the increased temperature, the cooking system 20 includes at least one vent for fluidly connecting the heating volume, and therefore the interior 34 of the cooking container 32, with the ambient atmosphere external to the cooking system 20. Although, the one or more vents are illustrated and described herein as being formed in a portion of the lid 24, it should be understood that vents arranged at another suitable location of the cooking system 20 are within the scope of the disclosure.

As best shown in FIGS. 16A-17C and FIG. 19, the cooking system 20 includes at least one inlet vent 100 through which a fluid is configured to flow into the heating volume and at least one outlet vent 102 through which a fluid is expelled from the heating volume. In an embodiment, each of the at least one inlet vent 100 and outlet vent 102 is operable to control a flow through the inner lid liner 42 and into or out of the heating volume. As best shown in FIG. 19, the inlet vent 100 and outlet vent 102 each include an opening 103 having an inlet end and an outlet end associated with or defined in the lid housing 40 and the inner lid liner 42, respectively. For example, the inlet end of the opening 103 of the inlet vent 100 is formed in the lid housing 40 and the outlet end of the opening 103 of the inlet vent 100 is located at the inner lid liner 42. Similarly, the inlet end of the opening 103 of the outlet vent 102 is arranged at the inner lid liner 42 and the outlet end of the opening 103 of the outlet vent 102 is formed in the lid housing 40. Accordingly, each of the openings 103 defines a fluid flow path extending between the ambient atmosphere surrounding the exterior of the lid 24 and the atmosphere within the interior 72 of the inner lid liner 42. In an embodiment, a conduit 105 may extend between lid housing 40 and the inner lid liner 42 to define one or more boundaries of a respective fluid flow path of the inlet and outlet vents 100, 102. However, in other embodiments, the portion of the fluid flow path extending between the interior 53 of the lid housing 40 and the exterior 55 of the inner lid liner 42 may be unbounded. In such embodiments, a pressure differential, such as resulting from operation of the air movement device 78 for example, may be sufficient to move a flow between the inlet and outlet ends of the fluid flow path of each of the inlet and outlet vents 100, 102, respectively. In yet another embodiment, the surface 55 of the inner lid liner 42 may directly abut the surface 53 of the lid housing 40 at the inlet and outlet ends of the openings 103. As a result, flow through the inlet end and outlet end of each opening 103 may be aligned and directly position next to one another such that a fluid flow passes directly between the body of the lid housing and the body of the inner lid liner 42.

With reference again to FIG. 3, the motor 80 may be arranged within a motor cavity 81 isolated from the remainder of the interior 44 of the lid 24. As shown, a motor cavity vent 104 may be formed in the lid 24 in fluid communication with the motor cavity 81. Air is configured to flow through the motor cavity 81 to cool the motor 80. In an embodiment, another air movement device 83 (see FIG. 4) is positioned within the motor cavity 81. This air movement device 83 may be driven by the motor 81 and is operable to facilitate a cooling flow into and out of the motor cavity 81.

One or more of the at least one inlet vent 100 and outlet vent 102 may be adjustable to control the amount of a fluid, such as air for example, provided to or exhausted from the heating volume. In an embodiment, each of the at least one inlet vent 100 and the at least one outlet vent 102 includes an element 106, such as a flap, slat, or another mechanism for example, that is movable to cover or expose at least a portion of the opening 103 of the inlet and outlet vents 100, 102, respectively. The at least one inlet vent 100 and the movable element 106 associated therewith may be considered a first venting system and the at least one outlet vent 102 and the movable element 106 associated therewith may be considered a second venting system.

In an embodiment, illustrated in FIG. 13, the movable element 106 is a flap or door arranged at an outer periphery of the inner lid liner 42 and movable vertically in and out of contact with an opening 103, With reference again to FIGS. 5-6 and FIGS. 15-17C, the movable element 106 may alternatively be arranged within the interior of the inner lid liner 42 adjacent to the outlet end of the opening 103 of the inlet vent 100 and the inlet end of the opening 103 of the outlet vent 102. In such embodiments, the movable element 106 is at a first position, at least partially separated from the opening 103 when the cooking container 32 is not pressurized. For example, as shown in FIG. 15, during an air fry operation, at least a portion of the movable element 106 is in a vertically lowered position, offset from the opening 103, such that air and steam are free to flow through the opening 103. However, once a pressure within the heating volume increases and exceeds a threshold, the pressure may be configured to act on and move the movable element 106. The force exerted by the pressure on the movable element 106 may move the element to a second position such that the movable element 106 blocks or seals the opening 103. Accordingly, when the movable element 106 is in the second position, such as during a pressure cooking operation for example, the movable element 106 seals the opening 103 thereby allowing the pressure within the cooking container 32 to increase. However, it should be understood that embodiments including a movable element 106 having another configuration and also embodiments where the movable element 106 moves in a different manner are also within the scope a the disclosure.

In an embodiment, a portion of the movable element 106 remains directly adjacent to the opening 103 as the movable element 106 moves relative to the housing 26 or lid 24. For example, the movable element 106 may have a first end 108 that remains generally fixed relative to an adjacent opening 103 and a second end 110 configured to move relative to the opening 103, thereby exposing at least a portion of the opening 103 to allow a fluid to flow there through. With reference to again FIGS. 16A-17C, in an embodiment, the second end 110 of the movable element 106 is configured to pivot or rotate relative to the opening 103. However, other types of movement, such as translation of the movable element 106 for example, are also contemplated herein.

In the illustrated, non-limiting embodiment, the movable element 106 is configured to rotate about an axis oriented generally parallel to the axis of rotation of the air movement mechanism 78. In such embodiments, the second movable end 110 may be configured to rotate inwardly toward a center of the lid 24. Accordingly, the flow path defined between the opening 103 and the rotated movable element 106 increases with respect to a direction of flow relative to the vent 100, 102. For example, in embodiments where the air movement mechanism 78, and therefore the air flow within the interior of the inner lid liner 42, is rotating in a clockwise direction, the downstream or trailing end of the movable element 106 associated with the inlet vent 100 is rotated inwardly. As a result, the portion of the opening 103 adjacent to the trailing end of the movable element 106 has a greater airflow capacity than portion of the opening 103 adjacent to the leading end of the movable element 106. Similarly, the upstream or leading end of the movable element 106 associated with the outlet vent 102 may be configured to rotate inwardly. As a result, the portion of the opening 103 adjacent the leading end of the movable element 106 has a greater airflow capacity than the portion of the opening 103 adjacent to the trailing end of the movable element 106.

In an embodiment, the position of the movable element 106 relative to the opening 103 is adjustable to control a flow through one or both of the inlet vent 100 and the outlet vent 102 in response to a selected mode or cooking operation of the cooking system 20. For example, during a first cooking operation, such as an air frying operation, the inlet vent 100 may be partially or fully open, so that a fluid may flow through the opening 103 into the heating volume (see FIGS. 5, 16A and 17A). Further, the outlet vent 102 may also be at least partially or fully open to allow air to exhaust from the cooking container 32, thereby preventing the pressure within the heating volume from increasing in response to the air flow being drawn into the heating volume and operation of the heating element 70. With reference now to FIGS. 6, 16B 17B, during a second cooking operation, such as a pressure cooking operation, the opening 103 of both the inlet vent 100 and the outlet vent 102 may be sealed or substantially sealed to block air from flowing into and out of the heating volume. In such embodiments, a high-pressure cooking environment may be achievable, with pressure levels reaching and/or exceeding 40 kPa. Similarly, in an embodiment, best shown in FIGS. 16C and 17C, during a third mode of operation of the cooking system 20, such as a combination pressure cooking and air frying mode, the inlet vent 100 may be partially or fully open and the outlet vent 102 may be sealed.

In an embodiment, the lid lock 52 is used to adjust the position of the movable element 106 of at least one of the inlet vent 100 and the outlet vent 102 to control the flow therethrough. As a result, a user may transform the lid lock 52 between a first configuration and a second configuration to selectively seal the one or more inlet and outlet vents 100, 102. For example, when the mode selector 60 is adjacent to or in contact with a first side of the opening 62 (FIG. 5, 16A) and therefore the lid lock 52 is in a first configuration, at least one of the inlet vent 100 and the outlet vent 102 may be open such that the heating volume is not sealed. Similarly, when the mode selector 60 is arranged adjacent to or in contact with a second, opposite side of the opening 62 (FIG. 6, 16B), and therefore the lid lock 52, is in a second configuration, both the inlet vent 100 and the outlet vent 102 may be sealed, and as a result, pressure can build within the heating volume. It should be understood that this movement of the mode selector 60 within an opening 62 of the lid housing 40 to drive rotation of the lid lock 52 is intended as an example only, and that any suitable configuration of a lid lock 52 that allows a user to manipulate the sealing surface 46, to selectively form a pressure-tight seal with the housing 26 or the cooking container 32 is within the scope of the disclosure.

In an embodiment, the interior surface 53 of the lid lock 52 may include a ramp-like feature (not shown) configured to cooperate with a biased plunger 112 used to mount the movable element 106 to a portion of the lid 24, such as the inner lid liner 42, adjacent to a respective opening 103. As the mode selector 60 is rotated within the slot 62, the ramp-like feature will engage and apply an increasing force to the plunger 112 opposing its bias. This force will cause the plunger, and therefore the movable element 106, to move, such as in a direction away from the opening 103 for example. Movement of the mode selector 60 in the opposite direction will move the ramp-like feature out of engagement with the plunger 112 and the biasing force acting on the plunger 112 will cause the plunger 112 to move back to a neutral position. In an embodiment, in the neutral position, the movable element 106 is positioned directly adjacent to the opening 103, to block the airflow therethrough. Although engagement of the ramp-like feature and the plunger 112 is described as moving the element 106 away from the opening 103, it should be understood that embodiments where the engagement of the ramp-like feature and the plunger 112 moves the element 106 towards the opening 103 and the bias of the plunger 112 moves the element 106 away from the opening 103 are also contemplated herein. Further, it should be understood that the cooperation between the lid lock 52 and movable elements 106 as described herein is intended as an example only and any suitable mechanism for adjusting a configuration of the at least one vent is within the scope of the disclosure.

Although a configuration of the inlet vent 100 and the outlet vent 102 is described above as being dependent on a cooking operation, in other embodiments, the vents 100, 102 may be alternatively or additionally adjustable in response to feedback from one or more sensors disposed within the cooking volume. For example, a temperature of a heating element or within the cooking volume may be monitored by the sensors and/or used to control a position of the movable elements 106.

With reference again to FIGS. 1, 4, and 6, a control panel or user interface 120 of the cooking system 20 is positioned adjacent one or more sides of the housing 26 or the lid 24, such as a front of the housing 26 for example. The control panel 120 includes one or more inputs 122 associated with energizing the one or more heating elements 70, 74 of the cooking system 20 by selecting and/or initiating a mode of operation of the cooking system 20. One or more of the inputs 122 may include a light or other indicator to indicate to a user that the respective input has been selected. The control panel 120 may additionally include a display 124 separate from or integral with the at least one input 122.

As shown in FIG. 18, a control system 126 of the cooking system 20 includes a controller or processor 128 for controlling operation of the heating elements 70, 74 and air movement mechanism 78 (including the motor 80 and fan associated therewith), and in some embodiments for executing stored sequences of heating operation. The controller 128 is operably coupled to the control panel 120, to the heating elements 70, 74, to the air movement mechanism 78, and in some embodiments, to the movable elements 106 for controlling a fluid flow through the inlet and outlet vents 100, 102. In addition, in an embodiment, one or more sensors S for monitoring one or more parameters (such as temperature, pressure, lid configuration, etc.) associated with operation of the heating elements 70, 74 may be arranged in communication with the controller 128. It should be understood that the sensors S may be the same, or alternatively, may be different than the sensors that provide feedback to control a fluid flow through the inlet vent 100 and/or outlet vent 102. In an embodiment, a first temperature sensor is located within the lid 24 proximate the first second heating element 70 and a second temperature sensor extends from a bottom surface of the liner 28 proximate the second heating element 74. In such embodiments, the first temperature sensor may be used, such as to monitor temperature for example, when the lid 24 is closed and the first temperature sensor S is arranged in fluid communication with the hollow interior 30 of the cooking system 20. The first temperature sensor may be used to monitor temperature in this manner, separately or in conjunction with the second temperature sensor.

As previously described, the cooking system 20 is capable of performing a plurality of cooking operations including a convective and conductive cooking operation. In such embodiments, the cooking operations include, but are not limited to air frying, pressure cooking, broiling, baking/roasting, dehydrating, slow cooking, steaming, searing, sautéing, and/or any combination thereof. To perform a cooking operation that includes a combination of multiple types of cooking modes, the food item need not be removed from the cooking container 32 as the cooking system 20 transforms between a first mode, such as a pressure cooking mode for example, and a second mode, such as an air frying mode for example.

The at least one input 122 may be used to select a mode or cooking operation of the cooking system 20. In an embodiment, the functionality of the control system 126, and therefore the inputs available to a user, may vary in response to the position of the mode selector 60 of the lid lock 52 and/or in response to the configuration of the one or more inlet and outlet vents 100, 102, which may be controlled by the mode selector 60. For example, one or more inputs 122 of the control panel 120 may be activated when the mode selector 60 is in the first position associated with a first cooking mode such as a conductive cooking mode, and one or more different inputs may be activatable when the mode selector 60 is in the second position associated with a second cooking mode, such as a convective cooking mode. Further, another group of different inputs may be activated when the mode selector 60 is in a third position, disposed between the first and second positions, and associated with a third cooking mode, such as a combination cooking mode. In an embodiment, one or more sensors, such as reed switches for example, may be mounted to the lid lock 52 to indicate to the controller 128 the position of the lid lock 52, and in response, a respective portion of the user interface 120 will be energized for selection by a user.

As previously described, the cooking system 20 may be operated in a cooking mode that uses conductive cooking. In the conductive cooking mode, the cooking system 20 may perform a pressure-cooking operation. In such embodiments, the lid lock 52 is affixed to the cooking container 32 or housing 26 to form a pressure-tight, sealed enclosure with the cooking container 32. During operation in the pressure cooker mode, the controller 128 initiates operation of the second heating element 74, causing the temperature and therefore the pressure, within the enclosure formed by the cooking container 32 and the interior of the inner lid liner 42 to rise. During operation in the pressure cooker mode, the heating element 70 disposed within the lid 24 is typically not energized. In embodiments where the cooking system 20 is operable in a pressure cooking mode, the liner 28 should be formed from a more rigid material capable of withstanding the pressure build up within the cooking container 32.

As is noted above, another of the cooking modes of the cooking system 20 employs convective cooking, for example to perform an air-frying operation. When utilizing the cooking system 20 in the air fryer mode, the controller 128 initiates operation of the first heating element 70 and the air movement mechanism 78 to circulate the hot air through the enclosure formed between the cooking container 32 and the inner lid liner 42. During operation in the air fryer mode, the second heating element 74 is generally not energized.

However, embodiments where the first heating element 74 is energized are also within the scope of the disclosure.

The air movement mechanism 78 draws air upward through the adjacent heating element 70 and expels the hot air outwardly towards a guide (not shown, and which, in an exemplary embodiment, actually surrounds the fan 78). The guide deflects the air downwardly towards the sides of the cooking container 32. The air travels down through an annulus 130 formed between the cooking container 32 and the basket 36 a until it is deflected off the bottom of the cooking container 32 and drawn up by the air movement mechanism 78 towards the diffuser 36 b and an end of the basket 36 a with an aperture pattern. The hot air flows over and between the plurality of vanes of the air diffuser 36 b, which impart a rotational motion to the hot air, thereby creating a vortex as the air is drawn through the apertures and into the interior of the basket 36 a by the air movement mechanism 78. After traversing the interior of the basket 36 a, the air is drawn back up through the heating element 70 and into the air movement mechanism 78 for further circulation.

As the air circulates through the cooking container 32, and specifically the basket 36 a, the hot air cooks and forms a crispy outer layer on the food items disposed therein as a result of the Maillard effect. In an embodiment, a liquid, such as oil or fat, is contained within the enclosure, such as at the bottom of the cooking container 32. The liquid may be added to the cooking container 32 prior to operation in the air fry mode, or alternatively, may be produced as a residual material as the hot air passes over the food within the cooking container 32. In embodiments where a liquid is disposed at the bottom of the cooking container 32, as the air circulates through the cooking chamber 34 of the cooking container 32, a portion of the liquid becomes entrained in the air flow and is heated.

During operation in any of the cooking modes of the cooking system 20, the controller 128 initiates operation of at least one of the first heating element 70 and the second heating element 74, causing the temperature within the cooking container 32 to increase. As previously described, the cooking system 20 may include one or more temperature sensors S for monitoring conditions within the cooking chamber 34. As is also previously described, a first temperature sensor may be arranged near the one of the heating elements 70, 74 and a second temperature sensor may be arranged near one of the heating elements or adjacent to the cooking container 32 to measure a temperature thereof. Upon detection that the temperature adjacent a heating element 70, 74 or within or at the cooking container 32 is equal to or exceeds a predetermined threshold, the controller 128 may de-energize the heating element 70, 74 until the temperature has returned to an acceptable level.

The cooking system 20 may additionally be configured to operate in another or third cooking mode that functions as a combination of two or more cooking modes. In the combination cooking mode, the cooking system 20 is configured to perform a first cooking operation and a second cooking operation sequentially and in response to a single input provided by a user. In an embodiment, during the first cooking operation of the combination cooking mode, a conductive cooking operation is performed and during the second cooking operation of the combination cooking mode, a convective cooking operation is performed. Further, the first cooking operation may be a steam, slow, or pressure cooking operation and the second cooking operation may be an air frying operation. In such embodiments, the controller 128 may execute a stored sequence where the second heating mechanism 74 is operated during a first portion of the sequence to perform the first cooking operation and the first heating mechanism 70 and air movement device 78 are operated during a second portion of the sequence to perform the second cooking operation. For example, in the combination mode, a food item, such as a chicken for example, may be steam or slow or pressure cooked via operation of the second heating element 74. Then, the first heating element 70 and the air movement device 78 may then be operated to air fry the chicken to achieve a crispy exterior layer. However, the embodiments described herein are intended as an example only and any sequence of operation combining both the first and second heating elements 70, 74 is contemplated herein. When operated in a combination of two or more cooking modes, the food need not be removed from the hollow interior 30, or more specifically the container 32 during such a transition.

As previously described, the cooking system 20 includes a plurality of temperature sensors operable to monitor a temperature within the cooking chamber 34. In the illustrated, non-limiting embodiment of FIG. 4, the cooking system 20 is shown as having two temperature sensors S1, S2; however, it should be understood that embodiments having more than two temperatures sensors are also within the scope of the disclosure. Further, although the temperature sensors S1, S2 are illustrated as being arranged at generally the same location relative to the cooking system 20, such as within a shared housing for example, in other embodiments, the temperature sensors S1, S2 may be located remotely from one another. These sensors S1, S2 may be affixed to the lid 24 and/or the housing 26 (or even the container 32) to sense temperature within the heating volume as defined by the container 32 and inner lid liner 42.

In an embodiment, one or more of the plurality of temperature sensors is a negative temperature coefficient (NTC) temperature sensor. Some NTC temperature sensors are designed to function more accurately at lower temperatures, such as between about 180° F.-245° F. (about 80° C.-118° C.) and other NCT temperatures sensors may be designed to function more accurately at higher temperatures, such as between about 245° F.-450° F. (about 118° C.-232° C.). In an embodiment, the cooking system 20 includes at least a first temperatures sensor S1 better suited for monitoring lower temperatures (referred to herein as a “lower temperatures sensor”) and a second temperature sensor S2 better suited for monitoring higher temperatures (referred to herein as a “higher temperatures sensor”). The lower temperature sensor S1 may be suitable for detecting the temperature within the cooking chamber 34 during a conductive or contact cooking operation. Similarly, the higher temperature sensor S2 may be suitable for detecting the temperature within the cooking chamber 34 during a convective or non-contact cooking operation.

The transition between the first and second cooking operations during a combination cooking mode may occur automatically in response to the temperatures detected by at least one of the lower temperature sensor S1 and the higher temperature sensor S2. In an embodiment, when operation of the cooking system 20 is initiated in the combination cooking mode, both the lower temperature sensor S1 and the higher temperature sensor S2 are operational and communicate signals indicative of a sensed temperature to the controller 128. The controller 128, however, will select which of the signals to read and/or rely upon based on the sensed temperature when compared to a predetermined threshold associated with that sensor. For example, if the sensed temperature measured by the lower temperature sensor S1 is lower than, for example 90° C., the controller will read signals provided by the lower temperature sensor. However, when the temperature sensed by the lower sensor S1 reaches or exceeds 90° C., the controller 128 will switch from reading the signals provided by the lower temperature sensor S1 to the signals provided by the higher temperature sensor S2. Similarly, if, after switching to the high temperature sensor S2 the sensed temperature measured by the higher temperature sensor S2 remains higher than, for example 90° C., the controller will continue to read signals provided by the high temperature sensor S2. However, when the temperature sensed by the high temperature sensor S2 falls to the threshold of 90° C. or below, the controller 128 may switch from reading the signal provided by the higher temperature sensor S2 to the signals of the lower temperature sensor S1. The thresholds provided herein are intended as an example only. “Switching” or threshold temperature can be in any desirable range such as 80° C.-130° C., 85° C.-125° C., 90° C.-120° C., or any low number and high number range between 80° C.-130° C.

The one or more temperature sensors S of the cooking system 20 may additionally be used to indicate to the controller 128 when to transition from a first cooking operation to a second cooking operation of the combination cooking mode. In an embodiment, the controller 128 may be configured to transition operation of the cooking system 20 from the first cooking operation to the second cooking operation in response to reaching a predetermined threshold temperature(s) (such as but not limited to those discussed above) associated with one of the lower and higher temperature sensors S1, S2, respectively. For example, the threshold temperature associated with the lower temperature sensor S2 may correlate to the temperature required for convective cooking within the cooking chamber 34. When the threshold temperature is reached, the controller 128 may automatically switch from conduction cooking via the lower heating element 74 to convection cooking via the upper heating element 70. Indeed, upon receiving a signal or identifying a condition indicating to the controller 128 to transition the cooking system 20 to the next cooking operation, the controller 128 will deenergize the second heating element 74 and will energize the first heating element 70 and the air movement mechanism 78. Upon transitioning to the second cooking operation, the same sensor or a different sensor than was being used to monitor the temperature during the first cooking operation may be operable to monitor the temperature in the cooking chamber 34. If different, the switch in cooking mode may coincide with the switch in temperature sensor being read (S1 or S2) as discussed above. In other words, reaching a sensed threshold temperature (such as but not limited to threshold temperatures in the ranges discussed above) may signal to the controller 128 to automatically switch just the temperature sensors S1 or S2 to be read, the cooking mode, or both the temperature sensors S1 or S2 to be read and the cooking mode to be executed.
